. lwardly-projecting nipples or attaching devices n, to which the individual cups are con- I nected by the passages or'pipes Z, andhaving in .its bottom portion alateralfpnipple or attacliingdevice (l, to which the main milk# pipe l-l. is connected. The chamber. mis pro- "vided below Athe lateral nipplewith afremovable bottom p', preferably secured by a screwthread, a packing-Washer p being interposed between the bottom and-thechamber.' Upon removing the hott'ointhe interior of the chamber and the' nipples are' full' exposed, so that these parts. can be readi y cleaned Withoutdisturbing the connection of the pipes with the nipples. y The pulsations are applied to the chamber` by the lateral nipple O andare equalizedby the chamber upon the several nipples; fn, Which connect With the t'eat-cups, so that all of the cupsoperate alike both' duringy the suction action and during the relieving action, thereby avoiding excessive action of the cups which are located "nearest the lateral'nipple or imperfect action ofthe cups which are located farthest from the lateral` nipple.

g represents an air-inlet formed in 'the chamber m of the connector for admitting a restrictedvoluinc of air to thel same and to the niillepassages connected therewith. This inlet is of such a restricted area with reference to the milliepassages that the volume of air entering through this inlet is insuflicient to materially affect the suction action W'iien suction is applied to the milk-passages, but issiifficient to considerably reduce the parL tial vacuum in the milk-passages when the suction is cut off from the saine. inlet in the connector furnishes a vconstant but restricted supply of air to the inilk-pas sages. l/Vlien the suction is cut ofi by thc pulsator, the air so supplied to the milk-pas .sages lrapidly relieves the vacuum in the saine. Thisair is admitted near, the teat cups and enters the milk-pipe m in the direction in which the milk iiows through the. same, thereby promoting the flow of the milk through the milk-pipe to the pail and preventing the surging of the milk toward the teat-cups and keeping the pipe clear of milk.

With milk pipes and teat-cups of ordinary 'dimensions air-iiilets of about one-twentieth mitted does not materially all'ef-.t the suction? The airbe 'used Without an'air-inlet in the pulsator,

, if desired. The constantvadmission of arestricted volume of air at the connector involves a little waste in re uiriiig a corre 'sponding increase of work y the exhaust apparatus; but this is compensated for by the improved operation of the mechanism and by its greater simplicity, the milking proceeding faster and better and the milktubes and passages being kept clean of milk.

The air-inlet in the connector is preferably protected by afilter-c'asing i", which contains 'cotton or some other suitable material r f or interceptin dust and other objectionable ingredients W ich may be contained in the air.

I claim as my invention- 1. In a inilkingfmachine, the combination with'teat-cups. and a millepipe, of an interposed connector comprising a 'body whichis open4 at the bottom, a bottom removably secured in the bottom opening ofthe body, a lateral attaching device for the milk-pipe formed on said body above the bottom openn ing thereof, and individual attaching devices for said cups formed on the top vof said body, the interior of said attaching devices being directly accessible upon' removing saidv bottom, substantially as set forth.

2. In a umilking-machine, the. combination of a milk-pipe, teat-cups, and a connector interpo'sed between said pipe and said cups and provided with a restricted air-inlet through which air is constantly admitted to the connector and the milk passages connected therewith, substantially as set forth.

3. In a milking-machine, the .combination of a milk vessel, a pulsator on the same, a

milk-pipe connected with the pulsator, teat` cups connected with the milk-pipe, an airinlet which is placed periodically in communication with the milk-pipe bythe pulsator, and an air-inlet which admits air constantly to the milk-pipe, substantially as set forth.

' 4. In a milking-machine, the combination of a milk vessel, a milk-pipeeonnected therewith, teat-cups connected with the milk-pipe, and'air-inlet devices adapted to admit a'ir to` both ends of'the milk-pipe, substantially as set forth. y

5. In a milking-machine, the combination of a milk vessel, a milk-pipe connected therewith, teat-cups, a connector interposed betwecnthe cups and the pipe and provided with an air-inlet which is constantly open,

and a pulsator provided With an air-inlet which is periodically placed in eommunica tion with the inilk-pipe, substantially as Aset forth..l
